Who works in the background to make sure a company’s IT infrastructure is always working, and is constantly fighting to prevent IT disasters from happening?
What factors are most important when planning for disaster and recovery? Check all that apply.
Correct
Well done! It’s super important to make sure that your company’s data is routinely backed up somewhere, preferably far away from its current location. If the entire facility is compromised, your data will still be safe.
Correct
Well done! Backups provide data redundancy in case of disaster. You can’t account for everything, but you can be prepared to recover from it.
As sysadmin, you will have to prioritize issues. Which of these issues would be a top priority?
As a sysadmin, you will find yourself doing business with a variety of third-party vendors. Which of these are likely to be rented or bought from a vendor? Check all that apply.
Correct
Great work! Fax machines are still alive and kicking at companies and they’re a big pain to deal with. Sysadmins could be responsible for requesting vendor service for those too.
Correct
Great work! Video or audio conferencing machines that need vendor service will probably need to be handled by the sysadmin too.
Correct
Great work! Sysadmins might be responsible for making sure printers are working, or if renting a commercial printer, they have to make sure that the vendor can be on-site to fix it.

An IT department uses a pre-used laptop out of their hardware inventory for a new user. Which stage of the hardware lifecycle does this scenario belong to?
When a machine is having issues, an IT Support Specialist has to file an RMA, or Return Merchandise Authorization form, with the vendor of the machine. Which stage of the hardware lifecycle does this scenario belong to?
The user can set their own computer hostname and username. Which stage of the hardware lifecycle does this scenario belong to?
A machine is having issues, so the user is responsible for getting the machine serviced. Which stage of the hardware lifecycle does this scenario belong to?
Microstrip is a type of electrical transmission line which can be fabricated using printed circuit board technology, and is used to convey microwave-frequency signals. It consists of a conducting strip separated from a ground plane by a dielectric layer known as the substrate. The most commonly employed microstrip antenna is a rectangular patch which looks like a truncated microstrip transmission line. It is approximately of one-half wavelength long. When air is used as the dielectric substrate, the length of the rectangular microstrip antenna is approximately one-half of a free-space wavelength . As the antenna is loaded with a dielectric as its substrate, the length of the antenna decreases as the relative dielectric constant of the substrate increases. The resonant length of the antenna is slightly shorter because of the extended electric "fringing fields" which increase the electrical length of the antenna slightly. An early model of the microst...
